VACUUM MASSAGE DEVICE.

To all whom it may concern.

Be it known that I, JOHN G. SCHLENTER,

' device of this character which shall be caing the vacuum creating member and a vacuum cup or applicator at the end of a flexible tube connecting wlth said member. Fig. 2 1s a bottom v1ew of the vacuum creating member showing. the elastic diaphragm.

Fig. 3 is a detail showing the means for coupling the flexible connection carrying the vacuum cup with the vacuum creating member to insure a tight joint.

Referring to the details, the vacuum creating member comprises a cup-shaped metal shell 1 over the open mouth of which is stretched an elastic diaphragm 2 of gum rubber, there being a sheet metal holding ring 3 between which and the margin 4 of the shell the margin of the diaphragm is firmly held. 5 is a tube connecting with the interior of the shell at 6 and the outer portion 7 of said tube is bent at an angle and the extreme end is made flaring, as at 9, to adapt the device for application to deep seated or wrinkled portions of the face, as for instance the portions immediately adjoining the nose and the eyes. It will be un- Specification of Letters Patent.

Application filed April 7, 1913.

Serial No. 759,436.

derstood that to create a vacuum it is simply necessary to hold the cup-shaped shell between the thumb and fingers, with the thumb resting upon the elastic diaphragm. By pressing the diaphragm and then releasing it a vacuum is created, the extent of the vacuum depending upon the depth to which the elastic diaphragm is depressed, being greatest when the diaphragm is depressed to the full depth of the metal shell and then released. By varying the initial pressure upon the diaphragm before it is released the vacuum may be increased or decreased at pleasure.

For the purpose of application to the cheeks, bust or other broad expanses of skin surface, it is desirable to use a larger cup than that of the end 9 of the tube 5 for the purpose of giving greater suction. It is also desirable that the cup have an unhampered movement over the expanded surfaces. I therefore provide an enlarged cup 10 or applicator having a nipple 11 to attach the same to the flexible tubular connection 12, and into the opposite end of the flexible connection 12 is inserted a nipple 13 having a screw end 14 adapted to be screwed into the end 9 of the tube 5, the end 9, being interiorly threaded for that purpose, 15 being a soft rubber washer on the nipple 13 adapted to seat upon the flaring margins of the end 9 and insure a tight joint.

Thus the device may be used with equal facility for massaging expanded, smooth skin surfaces or depressed or wrinkled portions.

l/Vhat I claim, is-

In a massage device, a hollow shell'of approximately semi-spherical formation, and having an open mouth, an elastic diaphragm disposed over and completely closing the mouth of the shell, said shell being formed with an outlet at a point farthest removed from the diaphragm, the full surface of the diaphragm being disposed for manual manipulation to expel any desired volume of air from the shell through the outlet.

In testimony whereof, I hereunto aflix my signature, in presence of two witnesses.
